OpenShift does support persistent volumes. Thinking about auto-scale I'm 
not sure that would help a lot though.

I'm wondering whether domain mode can help - having domain node(s) with 
persistent storage configuration for management. Then the worker nodes 
would read config from domain.

I suspect though most people would not want to waste resources for 
non-worker nodes and would expect to have things working OOB in some 
simple manner. Perhaps wildfly may support committing configuration 
changes in whatever format to some external system (git, file server, 
whatever), then read it from there.
e.g. if wildfly can commit any and all configuration changes to git, an 
OpenShift deployment config can trigger redeploy based on the noticed 
changes automatically (or user can trigger manually).

btw it would help if Wildfly records only changes from defaults (not all 
configuration files). In this way migrating between versions and 
changing defaults might work much smoother.
